- Appiicatio .med May s,

f-.Thisinvention relates-to"V door checks or stops and the"object`f;is to provide a neat. Vdurable and inexpensive Vdevice whichrmay be applied to doors,particularly kto the doors `of vehicles with closed bodies to 4limit the `opening movement thereof.`

My inventionv will best .be understood by reference to the following description of an illustrative embodiment.. thereof shown .by

.wayaof'example in 4the accompanying drawings, wherein: Y f ,Figa lisa horizontal section through -a portion of thehinge pillar of a vehicle bodj,7 and the adjacentyportion ofthe door, the door being in open position;` Fig.fg2 'is a Vsimilar view with :the door Fig. 3 is aside elevation of the stop with the parts extended into alignment;

Figay is an inverted plan thereof; and.

thefstrap. or loop commonly;,usedforr this ipurpose von vehicle ldoorsfan'd. provides a neater and'y more durable construction and also one'whichis exceedingly cheap to manufacture.` The, construction"A herein shown permitsthe .door to openl freelyand to stand open ifdesired. g 1 Referring particularly. to Figs. 1 and 2 v of the drawings, the stop maytake the form of a series 4of hinge leaves 7,9, 11 andv 13,'

the leaves 9 and 11 being adapted to extend, yas shown in Fig. 1, between points 'of the hinge pillar 15- and the hinge style 17 which separate from vone another inthe opening movement of the door'and form a foldable connection.adaptedfto'lie between the pillar.

and style and be housed in suitable mortises therein when the door is'shut, as shown in Fig. 2, and yto open out and extend substantially diagonally across the langle therebetween when the door is swunglopen,l as shown in Fig. 1. AIt-will'be obvious that as the leaves 9 `and11 come into alignment they serve as a connection across this angle between the door and the hinge pillar and prevent further swinging movement yof the CHEox .non poorts.'

AMESBURY,MAssAoirUsET'rs; a Conronnrioia on Messia;

doorabout its leaves f7 and 'y -13 Jprovide convenient 'q means for-securing the' ends of theleaves9. and 11 to the door I .andto the hinge pillar, they being-pref- .erably' attached by screwsto theinnerfaces of the.sameas shown; infFigs.` 1 andg2fo'f the drawing'. v -k t -f Thehingeleaves 7, 9, 11 and` 13 may con- =veniently be formed of flat, strips' offmetal rolled to form hingeknuckles.;` Asronsidverfable strain may come upon the, knucklesl preferably form the ends of the rolledportions". (see Fig. v5) with .tongues 21 adapted toextend through holes in the stripsuand be burredwover las at 23 inthe .mannerof rivets, thus providing vinv a convenient: and .inexpensive manner for very `fstrong knuckles? p My invention 'l particularly relates' to means for preventing-'the toggley formed :by

v.the leaves .9 andll (see Fig. 1 from throwing overpast dead, center inzorder that vit mayalways vcollapseand close, between the door an'dgthey hinge pillar in the manfnershownyin Fig. 2 and furtherto :means for mininiizingthe 'effect of the shoclrvwlnch is thrown vont-he stopby its action in.halt ing vthe swinging movement ofthe door."v

For .this purposey I 'providesuitable resilient means which will oppose the straightening out ofthe 4"toggle andvpreferablyfthis is 'ar- .ranged tol come intov `action onlywhenthe `linkshave nearly straightened out sotthat lthedoor may open freely land may ifdesired stand vopen in "the vposition of Fig. :lf'ivith- ,Qutfagny vtendency to`fre'cl0se. f To provide for these functions I may rivet to leaflli a Afiat spring25 having .its/end[extendingV past the ,hinge Joint/between the leaves 9- and '11 i and presented'to the back of the leaf 9 so:

vas to; come incontact therewith `andfloearl thereagainst l,when the leaves assume the po-v sition shown in Fig. 1 shortly before they come into alignment and to yield resiliently ifv the links are straightened outl into aligns ment as shown inl Fig. ,3. It. will be apparent that if the door isy swung open counteropenffreely without. any resistance until substantially 25fthenco1nes in contact` withleaf`9 and deflected bythe further straightening movement vof the toggle formed by the links 9 leaf lclockwise from the position-shown in Fig.` .2, the. leaves 9 and 11 will first' in the position of'Fig. l. The end of spring i and11. `.The limit of opening movement of. '110 the door, as *will be understood from Fig. l, is 'reached when the links do come into alignment. ln the latter part of this straightening action, therefore, the movement is cushioned and consequently a sharp Shock is not ythrown upon the parts particularly upon the knuckles and pintle connecting the leaves 9 and l1 which would tend to snap them. The reaction of the spring tends to return the leaves to the position shown `in Fig. l slightly off dead center so thatJ in closing movement of the door they collapse to the position shown in Fig. 2 in which position theyT are housed between the door and the hinge pillar. There is ino danger of their breaking in the 'reverse direction so that they would project into the linterior of the vehicle when the door was closed instead of returning to their inconvspicuous housed position.

'It will 'furtherbe apparentthat unless reverse breaking of the toggle were prevent- .ed the door might rebound and the tendency of vthe links ifolding in the other direction would beto draw it shut prematurely. ln the embodiment of the invention shown this is prevented and because the spring 25 works only during a very short time as vthe -door :approaches its extreme open position 'the door may be opened freely and7 while the sudden shock of stopping it is effectively cushioned, the lea-ves will be returned to the yposition shown in Fig. l somewhat .olf

center in a position to fold up properly 'without there being any undue tendency throughthe reaction of the spring completely .to reclose the door as in the case of spring hinges, commonly so-called, wherein opening lmovement is against the action of a spring.

"l have describedin detail ,the y'particular embodiment of my invention shownby way of `example in the accompanying drawings. 'Obviously the details of mechanical construction niay be considerably varied Without departing from `the spirit ofthe invention.

Vhat vl claim as new 'and desire to `se- `hinged leaves provided `.with `means .for .con-

nectingv .them to the hinge .pillar and V.hinge style, said lea-ves adapted to fold vbetween `pillar and style when the door is closed and extend substantially diagonally therebetween when iopenfand resilient means opposing the hinging of saidr leaves during the lattermost part'of their .opening movement only as they move vtoward alignment `whereby to yobviate sudden .shock on the check .as the door swings open.

2. A door .stop comprising a pair of hinged leaves provided with .means 'for .connecting them 't0 zthe .hinge pillar .and 'hinge' style, said Ileaves adapted to fold, between pillar and style when fthe door his Jclosedrand extend substantially diagonally therebetween when open and a liat spring secured to one leaf and having'anend presented to engage `the .other 'during 'the lattermost part only of the opening finovemen't o'flthe leaves as they approach alignment.

A door stop comprising a pair of hinged leaves provided with means for'connecting .them to the Ahinge pillar .and hinge style, said 'leaves adapted'to lfold between pillarand style when the-door isclosed and extend Asubstantially diagonally therebetween when open and l'a spring'stop which comes rinto action 'shortly before fthe leaves approach alignment 'to 'oppose 'further hinging movement of the leaves whereby to check sudden shock on the-hinge and to prevent reversal of the `same while leaving the door free to swing to and stand in open position.

4i. A stop hinge comprising a pair of leaves vpivoted together and a flat spring secured to one :leaf having #an end vextending over the pivot and p'resentedfto engage the other leaf only :shortly before Athe 'hinge reaches its desired maximum opening.`

ln testimony whereof, 'l lhave signed my name to this specification.
